Before TestView, a teacher would develop lesson plans and deliver her classroom presentation based on limited knowledge of the capabilities of his/her students. She presented her lesson to a "group".

After TestView, a teacher is able to craft her lesson plans and deliver her presentation based on detailed knowledge of an individual student's strengths and weaknesses. Now a teacher may use her creativity to accommodate certain students that she knows are at level 2, as well as challenge other students that she knows are at level 4. Lesson plans can be crafted toward the "individual student".
